Hmmmmmm...
Well, you have to set some perameters, determine a consumption budget and figure out how to recharge. You haven't really given us enough info. A thermo-electric cooler draws about 4.5 amps, a true fridge (efficient) about 7.5 amps...you can see it adds up quickly.Examples:1. You rarely go out for more than 1-2 days and can recharge with shore power.2. You have great solar gain in your area and want PV panels.3. The wind always blows where you are and you don't mind a wind generator.4. You would prefer a small, lightweight, quiet genset such as a Honda or Yamaha.Those are just some of the options. I have a 26x with a Kyocera solar panel (about 3.3 amps in full sun) on the hatch. I supplement with engine power and am playing with some small wind generators. I have a thermo electric cooler, stereo with CD changer, fans, evaporative cooler, lights, pressure water,GPS...I use more in a given 24 hour period than I produce. I sail mostly on the weekends and my two 110 amp deep cycle batteries can recharge during the week.Figure your consumption and then set a game plan.Let me know if I can offer any help.BOLK
